Handheld calculators have a lot to offer a student since they do more than just calculate equations. Many of the newer models have the accessibility of going on line to access information that can help you with your calculations. The newer calculators even have GPS capability for those who travel to a job site this is an excellent tool.

Uses of calculators

The calculators are very useful in this world of modern technology. You have many different professions like architects, designers, etc. who need the accessibility of a handheld calculator. The accountant who goes from business to business doing the monthly books needs a calculator. The student often needs a calculator in order to complete class studies. The problems that faced by students in math class can no longer are calculated by counting the fingers and toes. Math has grown into a complicated system that requires a calculator. Courses such as Algebra, Physics, and Calculus all require the use of the calculator. Texas Instruments started creating calculators in the last century that are internet ready along with the capability of saving the information stored to make it much easier for the user.

Calculators

The term calculators means to figure math facts to come to an equation that will simplify a problem. The definitions sounds as complicated as using a calculator but in reality most calculators are very easy to use. You can go on the internet and get teaching tools to help you learn how to use your calculator. The calculator itself often gives you examples to try so you can teach yourself how to use it. This is a better and more efficient way of doing complicated math problems.

Growing in Math Skills While Growing Up

!±8± Growing in Math Skills While Growing Up

Mathematics is one of the most crucial skills for a person almost anywhere in the world today. Mathematics is the bedrock for fields such as science, engineering, business, and technology. Whereas 200 years ago the main gateway skill for success in life was reading, today, math has become just as critical as reading for success in the world. Skill in mathematics translates to skill in computers and technology. But what's the trajectory for learning mathematics? How do children grow up to learn it?

In early years, children's mathematical learning is primarily confined to number sense. Number skills that are taken for granted in older children are noticeably absent in younger kids. While a young child may be able to mimic counting from 1 to 10, in most cases they don't really understand what those numbers mean. Younger children typically can't usually distinguish between groups of objects with similar numbers, such as 8 pennies versus 9 pennies. It's actually believed that humans are born to learn with a logarthmic sense of number, meaning it's natural for us to distinguish between 1, 2, 4, 8, etc., but not between 100 and 101. That's a skill that has to be taught.

As kids start in school and continue through elementary school, their numerical and mathematical skills get more concrete. As we are living in a base 10 world, students spend much of their time learning arithmetic (addition, subtraction, multiplication, and division) of the base 10 number system. Most children also learn best visually at this age. That is why you will see many classrooms utilizing tools such as base 10 blocks to learn the base 10 system, manipulatives to learn fractions, and the number line to learn positive and negative numbers. Kids also start to learn geometry skills. Again, these tend to be more concrete in nature, such as learning how to measure, the names and dimensions of shapes, even tessellations.

As students move into puberty and beyond, there ability to think abstractly grows substantially. For many students, middle school is the time that abstract thinking becomes easier to grasp. For others, it's not until high school. That's why many schools offer kids both the opportunity to take beginning algebra either in middle school or high school. As a young person's ability to understand the abstract grows, they can better grasp the concept of an unknown or variable. This gives them the capability to solve a variety of algebra problems such as solving equations. In American high schools, it's common to follow first year algebra with a year of proof-based geometry. The idea is that students are now capable of more advanced logical reasoning skills necessary for proofs. While some students enjoy the experience more than others, there's no doubt this same kind of logical reasoning is common to the sciences, computer programming, the law, and more.

As students finish high school and move into college, they take a variety of paths with their mathematical "careers." While some may only have to take a single general education math course, many others start learning a specific set of skills focused on their career. This could be anything from the advanced calculus and differential equations of engineering to the statistics necessary for a business career. Regardless of which direction they go, students will build on their early foundations of number sense, geometry, and abstract reasoning skills.

Computer - The Need Of Modern Life

!±8± Computer - The Need Of Modern Life

Computers simply mean a machine which can compute. Let us peek into the past and find out who were the geeks who thought about having a device that could perform calculative tasks by recognizing inputs and giving the appropriate outputs.

Abacus developed in 3000 BC can be called the first ever computer as it was a simple counting device. In 1941 a German engineer Konard Zuse developed a first programmable calculator using binary math and Boolean logic. UNIVAC was developed in 1951 and the real breakthrough came in 1952 when Texas Instrument developed the Integrated Circuit. In 1964, IBM introduced a mainframe computer called IBM 360. Apple introduced Apple I in 1976 and Apple II in 1977. The device that is familiar to most of us in terms of looks and functionality was unveiled in 1981 when IBM introduced the Personal Computer.

The main characteristics:

1 - It follows and is capable of following a special set of instructions.

2 - It can execute preset list of instructions generally known as a computer program.

The basic components:

1 - Input Device comprising of a Keyboard and Mouse which are used for entering instructions and data into the device.

2 - Output device such as the Visual Display Unit or the Screen, Printer etc, which lets us see what the device has done.

3 - The Central Processing Unit which is known as the brain where all the processing of data is done and instructions are executed.

4 - Memory is the powerhouse which stores data and instructions in it.

5 - Mass Storage Devices are those which permanently stores and retain large amount of data. The common ones are floppy drives, CD-ROMs, Hard disks etc.

Computers come in various types designed for various purposes keeping in mind different categories of its users. According to their type they have different capabilities and are priced accordingly. The most popular is the Personal Computer which is for personal use of a single user at one time. They come in two types; A Desktop and a Laptop. Then there is an even smaller models known as the Palmtop which can be held in the palms of the user. While these are the smaller and personal types, The Mainframe, Workstation and Supercomputers are the larger high end computers used by big organizations.

They can perform a wide range of functions such as word processing, Digital Audio/Video composition, Internet, Communications and Networking and Desktop Publishing. Word processing capability includes automatic correction of spelling and grammar mistakes. Internet is one of the greatest inventions of human beings. It connects infinite number of devices in the manner of a web.

Ungodly amounts of information are available on the Internet and facilities of communications such as messaging, audio and video conferencing are available for free. Graphic engineers are using computers for editing audio and video compositions. No media production can be completed without the help of these devices. Nowadays they are indispensable for Banking, Railway and Flight Reservations, Education and even defense of a country. There is hardly any sector of business which does not utilize these devices. Important and critical business tasks cannot be accomplished without the help of them.

Just like human beings, computers are also prone to diseases which are created by attack of viruses. Proper back up of all data stored in it must be maintained to provide back up in case of storage media failure. They must be secured from unauthorized use by passwords and must be protected from viruses by installing anti-virus programs in them. Computers, if safeguarded and used properly can create wonders for human kind and can produce results which are unachievable without them.

TI-Nspire, Future of Texas Instruments

!±8± TI-Nspire, Future of Texas Instruments

For over 15 years, Texas Instruments has owned the graphing calculator marketplace. Since the release of the TI-81 graphing calculator, TI has grown their following by improving that original TI-81 into the TI-82, TI-83, TI-83 plus, and eventually, the TI-84 plus. The TI-84 plus is still remarkably close to the TI-81. Despite the fact that the TI-84 has been incredibly popular, it's a dated device. Texas Instruments realized it was time for a new platform.

So in in 2007, Texas Instruments made public their new calculator, the Nspire. The improved features from the old product line were striking. On the old TI-84, the menus were odd at best, nonsensical at worst. It was hard for beginners just to figure out which button to push, and then the menu would fill the entire screen. With the Nspire, drop down menus are the norm, meaning students can stay in the screen they were working on and pull down a menu the way they would on a computer. Among other features are the highest resolution screen available on a calculator, the ability to save documents, a spreadsheet mode, mathprint for virtually all mathematical symbols, and a vastly improved system for graphing equations, simplifying the 84's ancient interface.

Frankly, the TI-Nspire made the TI-84 look like a dinosaur, and yet, the first reaction in the market was tepid. Why? TI didn't anticipate the reaction of two influential groups. First, despite positive TI-Nspire review s, educators were initially hesitant to adopt the Nspire. Many had just spent too much in the old TI-84. That was the case both in terms of the time invested learning the TI-84 and in terms of the school budget invested on classroom sets of TI-84 calculators. Texas Instruments tried to ease that consternation by offering a TI-84 keyboard that made the TI-Nspire look and act like a TI-84, but many felt that defeated the purpose of the Nspire. The other group that was cautious about the Nspire was the hacker community. At first, the TI-Nspire didn't offer programming as an option. Later, an OS upgrade offered some programming, but it wasn't enough to win over the programmers.

Lately, the Nspire has been gaining traction. Texas Instruments has noticed, getting rid of the Silver Edition of the TI-84. Now, however, TI finally faces competition from a competitor's calculator, not just its own TI-84. Casio has revealed its answer to the TI-Nspire. The Casio Prizm offers many of the same features as the TI-Nspire at almost the same cost, but offers two extra features with backlighting and the ability to display color pictures. The Prizm is set to be out in January 2011.

The Nspire finally has traction with buyers, but will face tough competition from the Prizm. The question now is whether the educator loyalty and user support they've created over the last 20 years will be enough for the TI-Nspire.
